Willie Hume demonstrated the durability of Dunlop's tires in 1889, winning the tire's first-ever races in Ireland and then England. The captain of the Belfast Cruisers Cycling Club, he became the first member of the public to purchase a bicycle fitted with pneumatic tires, so Dunlop suggested he should use them in a race. On May 18, 1889, Hume won all four cycling events at the Queen's College Sports in Belfast and a short while later in Liverpool won all but one of the cycling events. Among the losers were sons of the president of the Irish Cyclists' Association, Harvey Du Cros. Seeing an opportunity, Du Cros built a personal association with Dunlop, and together they set up a company that acquired the rights to his 1888 patent.
